This may not be the shortest, but should be easy to understand for anyone with a little bit of awk knowledge: awk '{ for (i = 1; I.

May I suggest: {print substr($i,4); break} in place of your print statement – glenn jackman Aug 9 '10 at 16:33 @glenn jackman Thanks, I added it. – schot Aug 10 '10 at 7:22.

Try: xinput --list | grep -Eo 'id=0-9+' | grep -Eo '0-9+' or xinput --list | grep -Eo 'id=0-9+' | awk -F= '{print $2}.

Nice solution. Requires GNU grep for -o – glenn jackman Aug 9 '10 at 16:31.

One way xinput --list | awk -F"id=" 'NF{split($2,a," ");print a1}' file with the shell(bash) #! /bin/bash xinput --list | while read -r line do case "$line" in *id=* ) line=${line##*id=} echo ${line%% *} esac done.

Try something like this: xinput --list | while read line; do ID=`echo ${line} | cut -d= -f2 | cut -d\ -f1 | xargs` echo ${ID} done.

Thanks it work fine! – turlutte Aug 9 '10 at 14:37 you're welcome :) – ozk Aug 9 '10 at 14:51.

Bash only: while read line ; do if $line =~ id=(:digit:) ; then echo "${BASH_REMATCH1}" fi done.

I find these things simplest with sed, using substitution of a group to capture the data you want and ensuring the rest of the line is matched in the regex. Sed 's/. *id=\(0-9*\).

Try: cat x | awk -Fid= '{print $2}' | awk '{print $1}.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
